原理:载入的时候只显示1号层,隐藏2-N号层.当你点击按钮的时候,隐藏1号层,并显示相应的层;
代码如下:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>滑动门通用JS</title>
<style type="text/css">
<!--
body{margin:0px;padding:0px;font-size:12px;background:#eee;line-height:20px;}
.bodyer{width:760px;margin:20px auto auto;border:1px dotted #ccc;background:#fff;}
.t_rt{text-align:right;}
h1,h2,h3,h4,h5,h6{font-weight:bold;margin:0px;padding:0px;font-size:12px;}
ul,li{margin:0px;padding:0px;}
li{list-style-type:none;}
h1{margin:10px;padding-right:10px;padding-bottom:5px;border-bottom:1px dotted #ccc;}
.preview{margin:10px;padding:10px;overflow:hidden;background:#eee;}
.cont{padding:10px;}
.cls{clear:both;}
.hidden{display:none;}
#sourse{border:1px dotted #ccc;width:600px;height:300px;margin:0px auto;}
.textDiv{margin:10px 40px 10px;text-align:center;}
h2{margin:0px 10px;background:#ccc;padding:5px;}
.example{margin:10px;background:#FFF;border:1px dotted #ccc;padding:10px;}
.scrolldoorFrame{width:400px;margin:0px auto;overflow:hidden;}
.scrollUl{width:400px;border-bottom:1px solid #CCC;overflow:hidden;height:35px;}
.scrollUl li{float:left;}
.bor03{border:1px solid #ccc;border-top-width:0px;}
.sd01{cursor:pointer;border:1px solid #CCC;background:#FFF;margin:5px;padding:2px;font-weight:bold;}
.sd02{cursor:pointer;border:0px solid #CCC;margin:5px;padding:2px;}
-->
</style>
<script type="text/javascript">
function scrollDoor(){
}
scrollDoor.prototype = {
sd : function(menus,divs,openClass,closeClass){
var _this = this;
if(menus.length != divs.length)
{
alert("菜单层数量和内容层数量不一样!");
return false;
}
for(var i = 0 ; i < menus.length ; i++)
{
_this.$(menus[i]).value = i;
_this.$(menus[i]).onmouseover = function(){
for(var j = 0 ; j < menus.length ; j++)
{
_this.$(menus[j]).className = closeClass;
_this.$(divs[j]).style.display = "none";
}
_this.$(menus[this.value]).className = openClass;
_this.$(divs[this.value]).style.display = "block";
}
}
},
$ : function(oid){
if(typeof(oid) == "string")
return document.getElementById(oid);
return oid;
}
}
window.onload = function(){
var SDmodel = new scrollDoor();
SDmodel.sd(["m01","m02","m03","m04","m05"],["c01","c02","c03","c04","c05"],"sd01","sd02");

自己修改css来实现不同的效果
按钮可以是图片,或者任意块级元素,也可以是链接;关键是id名称必须与JS里SDmodel.sd数组内一致.
